HOW WE WORK: THE BROKER ADVANTAGE

Why an independent data broker gives you better data

Marketing Data Lists (operated by AD Marketing) is a data broker – not a data warehouse. Many larger providers own a single proprietary dataset, which means you are limited to one source, one methodology, and one view of the market.

As an independent broker, Maxine Broadhurst has spent over 30 years identifying and securing relationships with the best specialist data suppliers in the UK – companies that each excel in specific sectors and use rigorous, telephone-verified and electronically researched collection methods.

This means you benefit from multiple high-quality sources, independently selected for accuracy and compliance, at the most competitive pricing available. You are not buying from a platform — you are buying from someone who knows every supplier in the market and selects the best one for your brief.

WHAT THIS MEANS FOR YOU

Access to the best
suppliers – not just one

Supplier network

Because we are independent, we select the supplier whose data is most accurate for your specific sector, geography, and campaign type.

You always get the best available data – not simply the data one company happens to own.

WHY OUR DATA OUTPERFORMS

Verified data vs scraped
data – a critical difference

Supplier network

Many providers scrape contacts from public sources with no telephone verification – which leads to high bounce rates and poor deliverability.

Our suppliers use direct verification calls and electronic cross-referencing, which is why clients report bounce rates well below the industry average.

HOW OUR DATA IS BUILT: COMPLIANCE METHODOLOGY

How our data is built – and why
compliance is guaranteed

Every record supplied by AD Marketing has been compiled through a rigorous, multi-stage research
and verification process carried out by our specialist suppliers.

Here is exactly how it works:

1
Telephone Research

Telephone Research – Direct Verification

Our data suppliers conduct live telephone-based research to collect and verify accurate business and contact information directly at source.

This involves direct calls to verify:
  • Company names and trading details
  • Current job roles and personnel
  • Live telephone numbers and email addresses
Telephone verification is the gold standard for data accuracy – it eliminates the high bounce rates associated with scraped or algorithmically generated datasets.
2
Electronic Research

Electronic Research – Digital Source Verification

Electronic Research – Digital Source Verification Data is additionally sourced and cross-referenced through structured online research including:

This involves digital cross-referencing of:
  • Company websites and published contact pages
  • LinkedIn profiles and professional directories
  • Companies House filings, Royal Mail PAF, and official government and sector registers

All electronically sourced records are checked for currency and relevance before being added to the database.

This dual approach – telephone plus electronic – means records are verified from multiple independent sources, not scraped from a single feed.
3
Email Collection

Email Collection & Article 14 GDPR Compliance

Whenever an email address is collected, a Personal Information Processing Notice is sent to that individual in line with Article 14 of UK GDPR.

This notice explains:
  • How their data will be used
  • The legal basis for processing (Legitimate Interests)
  • The individual’s rights including the right to object or opt out at any time

All electronically sourced records are checked for currency and relevance before being added to the database.

This process ensures every email address has been collected transparently and in full compliance with UK GDPR and PECR (Privacy and Electronic Communications Regulations)
4
Opt Out Management

Ongoing Transparency & Opt-Out Management

All marketing communications include a clear, functioning unsubscribe link – ensuring recipients can opt out at any time.
If any individual questions how their data was obtained, a dedicated compliance team responds promptly with full source details and a complete GDPR and PECR compliance explanation.

This means data is not only collected compliantly – it is managed compliantly on an ongoing basis throughout its use.

PROBLEM SECTION

Does this sound familiar?

Pain point 1
PAIN POINT 1

Campaigns reaching the wrong people

You are investing in outreach but missing decision-makers. Generic or unverified lists mean wasted budget and low response – because the data was never verified at source.

Pain point 2
PAIN POINT 2

Uncertainty about GDPR and PECR compliance

Compliance concerns hold marketing teams back. You need data that has been sourced, verified, and made compliant at the point of collection – with Article 14 notices issued and full documentation provided.

Pain point 3
PAIN POINT 3

Pipeline stalled – new leads needed

Referrals and inbound are not enough. You need a reliable route to verified UK B2B contacts across the sectors that matter, built to your brief by someone who knows the data market.

Pain point 4
PAIN POINT 4

High bounce rates from scraped data

Many providers scrape contacts with no telephone verification – records go stale and bounce rates climb. Telephone-verified data consistently outperforms scraped data on deliverability and open rates.

Testimonials

Don’t just take our word for it.
Here’s what our clients say.


★★★★★

Over the years, I’ve dealt with many different business data providers. My experiences have ranged from average to disappointing, to being downright ripped-off. That’s why it’s so refreshing to work with Maxine at Marketing Data Lists. She takes her client relationships and the quality of her data seriously. Most importantly, she NEVER sells me rubbish just to make a quick buck. All of Maxine’s data is not only high quality, but also GDPR compliant. If she does not have the data I need, she tells me — so I can trust that what I get from her will always be of great quality.

James Canter

Founder & Group Director, Reaction Group


★★★★★

Maxine helped us narrow down the sectors to exactly the right businesses, types/size and location for us. From initial contact to agreeing the data set, templates and printing/posting of letters, it only took a couple of days. We started with 500 letters and within the first two days received over 10 responses and counting. We are positive there is an acquisition in there for us — and this is thanks to Maxine. We will definitely use the service again.

Ross Hynd

HSE Consultant — Decommissioning & Restoration


★★★★★

I have always had great results when purchasing data from Maxine. I have worked with alternative providers and platforms, however I have often found some of their data to be incorrect or out of date. Maxine is always happy to help and talk through things. The fact she also offers a cost effective mailing service has proved very helpful.

David Williams

Land Owner Specialist


★★★★★

I have now been working with Maxine for a few months and can clearly state that she has tremendous expertise in her field. Marketing Data Lists’ service has been tailored, fast and of the highest quality. Where Maxine stands out is how she reads between the lines and helps you achieve what you are aiming for. I have already recommended Maxine several times and will continue to do so.
